   note: to have a generous belief in the greatness of one's
         country is not chauvinism. it is the character of the
         latter quality to be wildly extravagant, to be fretful
         and childish and silly, to resent a doubt as an insult,
         and to offend by its very frankness. --prof. h. tuttle.
